Support the Changing Standards for Treated Lumber

Posted 27 April 2016 3:09 PM by Jase DeBoer

We're embracing the recent ground contact standard changes set forth by the American Wood Protection Association (AWPA) in February of 2016.

The new standards released by the AWPA recommend that current above ground treated lumber applications must now adhere to (UC4A) ground contact requirements when they’re:

  • difficult to maintain, repair or replace (such as deck joists or ledger boards) and critical to the performance and safety of the entire system/construction
  • installed less than six inches from the ground
  • at risk for poor air circulation
  • likely to have prolonged contact with vegetation or leaf litter
  • exposed to frequent moisture
  • used in tropical climates

The new standards will eventually dictate building codes, so the transition to the new ground contact recommendations is imperative for code compliance, product reliability and, above all, safety.  We now offer a full line of products treated to (UC4A) ground contact standards, and they're still backed by a lifetime limited warranty.
